How to freeze sourdough
If you’ve ever bought a beautiful loaf of sourdough only to watch it go stale a day later, you’re not alone.
The good news? Freezing sourdough is one of the easiest ways to keep it fresh, reduce waste, and make great bread available whenever you want it.
Here’s exactly how to do it properly.
Why freeze sourdough
Freezing isn’t just convenient. It actually helps preserve the quality of your bread when done right.
- Less waste – use only what you need when you need it
- Better freshness – locks in texture and flavour
- Ultimate convenience – toast straight from frozen
The best way to freeze sourdough
1. Slice it first
Always slice your sourdough before freezing. This way you can take out exactly what you need without defrosting the whole loaf.
2. Store it properly
Keep slices flat and well sealed to avoid freezer burn. Freezer-safe bags work best because they protect the bread while keeping it easy to organise.
3. Freeze as soon as possible
The fresher the bread when it goes into the freezer, the better it will taste when it comes out.
Our sliced loaves are designed for freezing. Flat-packed in freezer-ready bags, they store neatly and make it easy to take out exactly what you need. No waste, no mess. It’s sourdough made to fit your routine.

How to defrost sourdough
The best part? You often don’t need to.
Option 1: Toast from frozen (recommended)
Pop slices straight into the toaster. This gives you a crisp exterior and soft centre in minutes.
Option 2: Defrost at room temperature
Leave slices out for 10–15 minutes if you prefer them untoasted.
If slices stick together
It happens. Simply place them on top of your toaster using the defrost setting. Let them warm slightly until they separate, then toast as usual.
Common mistakes to avoid
- Freezing a whole unsliced loaf
- Using non-airtight packaging
- Leaving bread out before freezing
